摘要:
为改善水滑石(LDH)与聚合物基体相容性差、阻燃效率低的问题,利用离子交换法制备了十二烷基硫酸钠(SDS)和硼酸复合改性的水滑石,并将其作为阻燃剂,经熔融共混法制得PP/LDH复合材料。采用红外、XRD、SEM和TGA对改性水滑石的结构、形貌和性能进行分析,利用极限氧指数仪和锥形量热仪对PP/LDH复合材料的阻燃性能进行分析。结果表明:复合改性方法有效扩大了水滑石的层间距,改善了其与PP基体间相容性,有利于LDH阻燃剂在PP中的均匀分散。复合改性LDH的添加大大提升了PP/LDH复合材料的阻燃性能;当向PP中添加质量分数为20.0%的阻燃剂时,该材料的极限氧指数值由纯PP的18.0%提升至30.9%,热释放速率峰值由纯PP的1215.84 kW/m 2下降至50.70 kW/m 2,烟释放总量由纯PP的12.66 m 2下降至6.15 m 2。该研究为高阻燃性能聚丙烯的制备及应用提供了策略支撑。
